As for when the mosquito feeds:

"The biting activity of Aedes aegypti is greatest in the morning for several hours after daybreak, and in the late afternoon for several hours before dark. However, this mosquito sometimes feeds throughout the entire day indoors, in areas protected from direct sunlight or on overcast days. Aedes aegypti may sometimes feeds indoors during the night if lights are turned on."

Also regarding the incubation period:

"There is an incubation period of 3-14 days (usually about 4-7) between the bite from an infected mosquito and the onset of dengue symptoms."

"Reducing time spent in residential areas may reduce your possible exposure to the mosquitoes carrying the dengue virus."

Can a person have dengue more than once?

"Four related viruses cause dengue: DEN-1, DEN-2, DEN-3, and DEN-4. Thus a person can have up to four dengue illnesses in a lifetime if exposed to each dengue virus. Since 1980, the number of new dengue cases has increased dramatically in tropical countries worldwide."
